Controlling the transport of an ion: Classical and quantum mechanical solutions
H. A. Fürst, M. H. Goerz, U. G. Poschinger +6
We investigate the performance of different control techniques for ion transport in state-of-the-art segmented miniaturized ion traps. We employ numerical optimization of classical…
Optimal control theory for a unitary operation under dissipative evolution
Michael H. Goerz, Daniel M. Reich, Christiane P. Koch
We show that optimizing a quantum gate for an open quantum system requires the time evolution of only three states irrespective of the dimension of Hilbert space. This represents a…
Steering the optimization pathway in the control landscape using constraints
José P. Palao, Daniel M. Reich, Christiane P. Koch
We show how additional constraints, restricting the spectrum of the optimized pulse or confining the system dynamics, can be used to steer optimization in quantum control towards d…
Cooling molecular vibrations with shaped laser pulses: Optimal control theory exploiting the timescale separation between coherent excitation and spontaneous emission
Daniel M. Reich, Christiane P. Koch
Laser cooling of molecules employing broadband optical pumping involves a timescale separation between laser excitation and spontaneous emission. Here, we optimize the optical pump…
Time optimization and state-dependent constraints in the quantum optimal control of molecular orientation
M. Ndong, C. Koch, D. Sugny
We apply two recent generalizations of monotonically convergent optimization algorithms to the control of molecular orientation by laser fields. We show how to minimize the control…
Optimal control under spectral constraints: Enforcing multi-photon absorption pathways
Daniel M. Reich, José P. Palao, Christiane P. Koch
Shaped pulses obtained by optimal control theory often possess unphysically broad spectra. In principle, the spectral width of a pulse can be restricted by an additional constraint…
Optimal strategies for estimating the average fidelity of quantum gates
Daniel M. Reich, Giulia Gualdi, Christiane P. Koch
We show that the minimum experimental effort to characterize the proper functioning of a quantum device scales as 2^n for n qubits and requires classical computational resources ~…
Minimum number of input states required for quantum gate characterization
Daniel M. Reich, Giulia Gualdi, Christiane P. Koch
We derive an algebraic framework which identifies the minimal information required to assess how well a quantum device implements a desired quantum operation. Our approach is based…
Comparative study of monotonically convergent optimization algorithms for the control of molecular rotation
M. Ndong, M. Lapert, C. Koch +1
We apply two different monotonically convergent optimization algorithms to the control of molecular rotational dynamics by laser pulses. This example represents a quantum control p…
